Notify
This feature is supported in mobile applications only.
The notify component displays a container in a particular region of the parent object. It can receive some content, and can be automatically hidden after a certain amount of time.

Adding a Notify Component
The following example shows how to create a notify object.
Evas_Object *notify, *parent; notify = elm_notify_add(parent);
Configuring the Notify Component
Create a label and add it to the notify object.
Evas_Object *content; // Create the label and set some text to it content = elm_label_add(parent); elm_object_text_set(content, "A label text"); evas_object_show(content); // Add the label object to the notify component elm_object_content_set(notify, content);
In the following example the notify object is shown on the bottom left corner of the parent object.
elm_notify_align_set(notify, 1.0, 1.0); evas_object_show(notify);
Set a timeout interval, after which the notify component is hidden. In the following example the timeout interval is five seconds.
elm_notify_timeout_set(notify, 5.0);
Using Notify Callbacks
The notify component emits the following signals:
- timeout: The timeout count ends and the notify component is hidden
- block,clicked: The user clicks outside of the notify component
For both these signals event_info is NULL.
The following example shows how to register a callback on the timeout signal.
{ evas_object_smart_callback_add(notify, "timeout", timeout_cb, data); } // Callback function for the "timeout" signal // The timeout expires and the notify object is hidden void timeout_cb(void *data, Evas_Object *obj, void *event_info) { dlog_print(DLOG_INFO, LOG_TAG, "Notify is hidden\n"); }
